| Description | Construction view of the Zero Gradient Proton Synchrotron (ZGS), the huge atom smasher at the Argonne National Laboratory, Argonne, Illinois. The photograph was taken looking south in November, 1960, and shows structural steel being put into place for a 210-foot doughnut-shaped building which will house a 5,000-ton ring of eight steel magnets that forms the heart of the atom smasher. Protons, sub nuclear particles, will race around the magnet ring until they attain energies of 12.5 billion electron volts. Foundations for the magnets are already in place. A 90-foot high structure in the center of the doughnut will house power supply and cooling equipment for the magnets. A cooling tower is shown in the left hand corner of the picture. Purpose of the ZGS, to be completed in 1962, is to find out new information about the basic nature of matter. It will be one of the largest and most powerful atom smashers in the world. |
